According to the CDC, the outbreak has been linked to recalled iceberg lettuce distributed by Taylor Farms de Mexico. Federal investigators are continuing traceback efforts to determine the full scope of the contamination.

As of the latest update:

Cyclospora cayetanensis is a microscopic parasite that causes cyclospora infection (cyclosporiasis), an intestinal illness spread through contaminated food or water.

Common symptoms include:

• Watery diarrhoea

• Stomach cramps

• Loss of appetite

• Nausea

Symptoms typically appear about one week after exposure and may persist or recur if left untreated.

What should consumers do?

• Seek medical care if symptoms develop after eating potentially contaminated produce.
